1-[2,4,6-Trimethyl-3,5-bis­(4-oxopiperidin-1-ylmeth­yl)benz­yl]piperidin-4-one

In the structure of the title compound, C27H39N3O3, each of the (4-oxopiperidin-1-yl)methyl residues adopts a flattened chair conformation (with the N and carbonyl groups being oriented to either side of the central C4 plane) and they occupy positions approximately orthogonal to the central benzene ring [Cbenzene—C—Cmethyl­ene—N torsion angles 103.4 (2), −104.4 (3) and 71.9 (3)°]; further, two of these residues are oriented to one side of the central benzene ring with the third to the other side. In the crystal packing, supra­molecular layers in the ab plane are sustained by C—H⋯O inter­actions

1-Chloro­acetyl-3-isopropyl-r-2,c-6-diphenyl­piperidin-4-one

In the title compound, C22H24ClNO2, the piperidine ring adopts a distorted boat conformation. The dihedral angle between the two phenyl rings is 83.2 (1)°. In the crystal, the mol­ecules are linked into chains running along the b axis by C—H⋯O hydrogen bonds. The Cl atom of the chloro­acetyl group is disordered over two positions with occupancies of 0.66 (2) and 0.34 (2)

3-Isopropyl-2,6-bis(4-methoxyphenyl)piperidin-4-one

In the title compound, C22H27NO3, the piperidine ring adopts a slightly distorted chair conformation. The dihedral angle between the two aromatic rings is 60.4 (1)°. In the crystal, the amino group forms a rather long N—H...O contact to a methoxy O atom. There are also C—H...O interactions present

In the title compound, C23H25Cl2NO4, the piperidine ring adopts a distorted boat conformation. The dihedral angle between the benzene rings is 54.8 (1)°. In the crystal, the molecules are linked into a two-dimensional network parallel to the ab plane by C—H...O hydrogen bonds
